| 1. | It is generally recognized that emulsions having a small particle size and a homogeneous distribution are more stable 乳剂通常被公认为有一个小的粒子形状并且同类的分区会更加稳定。 |
| 2. | Parabolic component gradient variation of gf improves 18 % of gf homogeneous distribution on bending strength ; linear component gradient variation only does 6 % 抛物线梯度分布组28天抗弯强度比均匀试件提高达18 ,而线性梯度提高6 。 |
| 3. | Nr1 subunit is widespread in the nervous system , whereas the expression of nr2a - 2d subunits , with distinct developmental and regional patterns , is generally more restricted than the homogeneous distribution of nr1 subunit Nr1广泛表达于全脑,而nr2亚单位的表达在发育阶段和脑区分布各不相同。 |
| 4. | It is now known that using powder with fine particle size and homogeneous distribution of ingredients can improve the sinterability of a powder compact , especially in w - cu system , for which the dominant sintering mechanism is particle re - arrangement during the liquid - phase sintering 而超细、混合均匀的粉末能较大地改善粉末的烧结性能,对以颗粒重排机制为主导的w - cu系液相烧结尤为如此。 |
| 5. | The results indicated that discontinuity of micro structure of work layer caused by in . homogeneous distribution of chemical composition , different pattern of carbide , mhomogeneity of hardness lead to large area of spalling and frther scrapping of roll 结果表明,化学成分的不均匀分布,造成轧辊辊身工作层组织不连续、碳化拘形态各异使辊身工作层硬度不均匀,产生大面积剥落,最终导致轧辊报废。 |
| 6. | ( 3 ) compared with that of the homogeneous distribution of the high strength aggregates and the activation aggregates , the higher strength of the gradient distribution of the disperse phase of the cement - based fgm are achieved , especially the bending strength 通电后迅速发热,随着时间的延长升温速度变缓(电阻增大) ,最终达到发热和散热的平衡而使温度恒定; ( 3 )不同性能骨料的梯度分布可带来比其均匀分布优越的力学性能。 |
| 7. | Linear component gradient variation of aggregates improves 16 % of aggregates homogeneous distribution on bending strength ; parabolic component gradient variation does 8 % . gf is widely used as composite reinforcement due to low cast and excellent properties such as high tensile strength and high elastic modulus 抛物线梯度不如线性梯度增强效果好,线性梯度变化比均匀分布试件抗折强度提高了16 ,抛物线梯度提高了8 ;玻璃纤维的高抗拉强度及较高的弹性模量,提高了纤维混凝土复合材料的拉伸强度和弹性模量。 |
